Description

[Detailed description of the invention] [Industrial application field] This invention places a moving vehicle on a moving frame suspended from an endless chain, and moves the moving frame vertically and horizontally in a meandering manner. This relates to a circulating mobile parking facility that stores moving vehicles by changing direction, and is particularly designed to prevent the movable frame from swinging when moving in the vertical direction, and to prevent the movable frame from falling in an emergency such as cutting an endless chain. This invention relates to a circulating multi-level parking lot facility that can prevent accidents.

[Conventional technology] Conventionally, a moving vehicle is mounted on a moving frame suspended from an endless chain, and the vehicle is circulated within the frame to construct a three-dimensional parking space, which efficiently fills a limited land area. Circulating mobile multilevel parking facilities for storing moving vehicles have been proposed.

However, in this case, the moving frame is suspended from an endless chain within the frame and is configured to circulate along an elliptical moving path, and the total weight of the moving vehicles mounted on the moving frame is Approximately half of the load becomes the load on the endless chain, so the strength of the frame supporting the endless chain and the strength of the endless chain itself must be increased, and the capital investment per moving vehicle becomes expensive. It had the following drawback.

Therefore, in order to eliminate the above-mentioned drawbacks, the present inventor proposed in Utility Application No. 59-234473 that a chain guide wheel was disposed in the moving path of the endless chain, and the moving frame meandered in the vertical and horizontal directions. We proposed a circulating multi-level parking facility that can be constructed with low capital investment by constructing the parking structure so that the direction of movement can be changed in a manner that increases the strength of the framework that supports the endless chain and reduces the load on the chain itself. However, with this method, although the strength of the endless chain and the strength of the frame supporting the endless chain can be kept low enough to meet the needs, the movable frame suspended from the endless chain moves in the vertical direction. When moving, there is a risk that the movable frame may swing and come into contact with an adjacent movable frame or the moving vehicle on which it is placed, causing damage. Not only is it not possible to improve the efficiency of entering and exiting a multi-level parking facility, there is also no consideration given to preventing accidents due to cutting of the endless chain, etc., and the direction of movement of the endless chain is not driven. There is also a fear that the endless chain may fall off from the chain guide wheel due to the loosening of the endless chain that occurs when the device is reversed, and safety measures have not been taken as a multi-level parking facility. It had the following drawback.

[Problem to be solved by the present invention] In view of the above-mentioned actual situation, the present invention was devised in order to eliminate the drawbacks of the conventional technology. In a circular movable multilevel parking facility configured to circulate an endless chain that suspends a movable frame in a meandering manner in the vertical and horizontal directions, the movable frame is prevented from swinging when the endless chain moves vertically. Not only can collision accidents between the moving frame and the moving vehicle be prevented, but also the moving speed of the moving frame can be increased, making it easier for moving vehicles to enter the multi-story parking facility.
Not only can it improve the efficiency of unloading, but also in the event of an emergency such as the endless chain suspending the moving frame being cut or falling off, it can prevent the moving vehicle from falling due to the endless chain slipping, and the above-mentioned The present invention aims to provide a circulating multi-level parking facility that can always ensure the safety of moving vehicles.

[Means for Solving the Problems] In order to solve the problems, the first technical means adopted by the present invention is an endless chain for suspending a moving frame on which a moving vehicle is mounted, and an endless chain for driving the endless chain. and a chain guide wheel disposed in the movement path of the endless chain to change the moving direction of the moving frame in a meandering manner in the vertical and horizontal directions. The movable frame is provided with a movable wheel that moves on the floor while being guided by guide rails at a position that precedes the lower end of the movable frame in the direction of movement. As a second technical means, the chain guide ring body is provided with a chain protector spaced apart from the outer periphery of the endless chain to be suspended. In addition to mounting, the chain protector is characterized in that a chain locking pawl is obliquely provided on the inner wall of the chain protector.

[Operation of the invention] Therefore, according to the invention, there is provided an endless chain for suspending a movable frame on which a moving vehicle is mounted, a drive device for driving the endless chain, and a drive device for driving the endless chain in the moving path of the endless chain. Vertical movement of a movable frame suspended from an endless chain in a circulating multi-story parking facility equipped with a chain guide wheel arranged to change the direction of movement of the movable frame in a meandering manner vertically and horizontally. At times, it is possible to prevent the movable frame from swinging, and in an emergency such as cutting or falling off of the endless chain, it is possible to prevent an accident of the movable frame from falling.
